MANUFACTURE OF GLASSWARE.

Application filed April 24, 1925, Serial No. 25,573, and in France May 1, 1924.

The present invention relates to the man- I ufacture of glassware such as bottles, flasks, jars or the like,by the system in which'a molten glass by suebrought into contact body of molten glass receptacle, and sucwithinthe mold to tion,-the mold being withjthesurface of a in a'lifu'rnaceuor other tion being produced In the existing installations the gathering of glass by the machines always takes place at the same point in the furnace. These repeated gatherings cause the glass the end of a certain time the machine ceases to work well.

According to the present invention, the machine suitable for the fabrication of the glass articles is displaced with respect to each gathering operation, and the point of aspiration in the glass is thus constantly changed.

Moreover, burners are provided on both sides of the gathering zone in the furnace, the burners being put into action after each gathering ormration, thus reheating the place in the furnace where the gathering has just been effected. l V

The displacements of the machine with respect to the furnace can be accomplished in any suitable manner, for example, by a neumatic control as, described in French l atent No. 581,003 and in application'filed on tliisdate. Serial No. 25,574; These displacements of the machine may be accomplished equally well by means of an electrical control, a mechanical control, or even a hand control. The same is true with regard to putting into and out which serve to reheat the gathering zone in the furnace.

"he accon'l'panying drawing shows diagrammatically, upon asection cut horizontally through the furnace, an arrangement ,for applying thelnethod forming the object of the invention to an installation comprising a double series of molds.

As shown, the gathering operations in the furnace a, which is closed by a door a, take at two places for the The vertical move putinto and out of ac two series of molds. ments of the door a tion the burners I), I1,

As shown, two blank molds, serving two identical series of mechanisms, gather the glass at the points' c, a. Afterthis operation, the machine is displaced longitudinalin such a way as to approach the fur naco; the two gathering operations then take place simultaneously atthe two points 0 ,0". uring the next gathering operation, the glass is gathered at the p0ints c, c after another longitudinal displacement of the machine. 7

Through a transverse displacement of the machine, the glass is then gathered simulta? neously at the points a, a. Then,,the machine being left in the same position in the transverse sense, but being displaced longitudinally so as to recede from the furnace, simultaneous gathering operations place at the pointsc 0" and then at points 0, 0''.

Through another transverse displacement of the machine, gathering operations are the take

nal displacements of the machine in respect as well as the number of the displacements, which depends on the dimensions of the furnace. These displacements of the machine can be accomplished in nor, by pneumatic control by liquid pressure, by an electrical or mechanical control, or even by a hand control. The same is true in regard to the control of the burners b, b for reheating-the gathering places, control of which is preferably accomplished automatically through the movements of the furnace door a before and after each gathering operation i ,The invention has been described, by way of example, in connection with its applica we to an installation comprising two series isevident that it can be 'to the furnace may evidently be n'iodified,

Priority under the lnternationalconvention for the Protection of Industrial Property of March 20, 1883, is claimed for the present application, by reason of the filing in France on May 1, 192i, of a corresponding application for French Letters Patent, upon which French Patent No. 581,602 was granted on September 17, 1924, to my assignce, the Socit dEtudes. et'dEXploitations Verrieres'.

I claim:

1. The glass-working method which comprises periodically applying a gathering implement to the surface of a stationary supply of molten glass, and, in ,the intervals between such gathering operations, directing a flame upon the region of the glass surface where said gathering takes place, to reheat suehportion of the glass as may be chilled by contact with said gathering im-,

leme-nt.

2. The method of gathering molten glass from a supply in a container having a normally closed workopening above the glass level, which comprises uncovering the work opening, inserting a gathering implement into said container through said openin", obtaining a gather of glass from the supply, withdrawing said implement, closing sai work opening, and then directing a heating medium to the portion of the glass in the container from which the gathering operation has taken place.

3. The method of gathering successive mold charges of glass from. a supply in a container having a normally closed workopening above the glass region, which comprises a periodic eyeleiof steps, including uncovering said work opening, inserting a gathering implement through said opening, gathering a portion of the glass from the surface of said supply at a point removed from the point on said surface engaged preceding gathering operation, withdrawing said implement, closing said opening, and directing a heating medium to the region of the surface of the glass in the container within which said gathering operations take place.

4. Glassworking apparatus comprising a stationary container for a supply of molten glass, said container being provided with an opening through which gathering implements may be inserted, a. door movable to and from position to close said opening, burner openings in the wall of said contamer adjacent to'opposite sides of said first-named opening, and burners for projectingflame through said burner openings in converging directions upon the surface of the glass in saidcontaincf.

5, (llassworking apparatus comprising a stationary container for a supply of molten glass, said container being'provided with an opening through which gathering implements may be inserted, a door movable toand from position to close said opening,

burner openings in the wall of; said container adjacent to opposite sides of said. first-named opening, burners for projecting flame through said burner openings in converging directions upon 7 glass in said container, and'means'for turning on said burners when said door closes and for turning off said burners when, said door opens.

6. In combination with-a glassmelting container having a work openi-n means for supplying and for directing a eating medium to the glass near the work opening,-

a door for the work opening, and means operated in synchronism with the opening or closing of the door for regulating the supply of heating medium.

7. In combination with container having a work opening therein, a door for the work opening, means for directing a heating medium to the lass in the container near the opening, an means the surface of thea. glass melting v actuated by the movements of the door for controlling the operation of the heat directing means. 1

8. In combination with a container for molten glass havin a work opening above the glass level for t e reception of a gathering implement, a. door for the pening, said door a'rrangedto be opened (1 closed at each gathering operation, meansfor applying 'a heating medium to the surface of the glass near the opening, and means operated in synehronism with the opening of the door for regulating the application of the heat-in medium.
